Gasoline Particulate Filter (GPF)

Gasoline Particulate Filters (GPFs) are also called OPFs (Otto Particulate Filters, named after the Otto cycle) or PPFs (Petrol Particulate Filters). The primary purpose of a Gasoline Particulate Filter (GPF) is to capture and remove harmful, ultra-fine particulate matter from the exhaust gases of gasoline engines before they escape into the atmosphere. In many countries, they are mandated for use on vehicles with direct fuel injection technology – between 75% and 98% of new vehicles sold in the US are equipped with Gasoline Direct Injection (GDI) engines.
